Your model uses two STK392-560 ICs and you will also most likely need at least twp 3.5 amp pico fuses. You can get replacement parts with free instructions at the following link.

I have an rca r52wh77 it is bowed in the top and bottom. it also is way off in convergence and i can not seem to get the crosshatches to come together. i have changed the fl123 part that was sent in my kit...


Does the kit have a pair of convergence ICs? That is what you will need to fix the convergence problem. The kit should also contain thermal grease(a white paste that should be applie to the ICs before you solder them) and resistors that may also need to be replaced. When a convergence IC blows its usually due to failed resistors.

I have a panasonic PT-47wxc43 projection tv. I have green and purple halos coming up from the bottom. The screen has purple and green double images which are worse from the bottom up.


Hi,
This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

My samsung rear projection tv has a problem with its convergence ic. i think theres two ics , but how do i tell which ic need replacing??


Always replace both once your going to the trouble each IC is usually less than $30.
This link will help show you what's involved.
convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Replaced ic chips and still have red convergence problems


convergence resistors they can often be burnt open when the ICs go out.

Burnt resistors


Depending on where you bought the ICs you could have fried the new ICs when powering it up with burnt resistors as the green is controled by both ICs one IC controling the horizontal green Convergence and the other IC controling the vertical green convergence. Have you checked all the convergence resistors out of circuit?

HC-P4752W - IC Replacement vs Convergence Module.


The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.
